Article Synopsis
  • A recent outbreak of the Madariaga virus (MADV) in Panama has raised concern, particularly following a fatal infection in June 2017, alongside the circulating Venezuelan equine encephalitis virus (VEEV).
  • A study conducted in July 2017 uncovered low seroprevalences of MADV (1.6%) and VEEV (4.4%) but revealed higher IgG antibody levels, indicating prior exposure in the population.
  • The investigation also suggested a historical endemic presence of alphaviruses in the region, with recent increases in human exposure to MADV and VEEV, although severe cases remain rare, highlighting a complex interaction between these viruses and their environmental transmission dynamics.

Despite the importance of Aedes, Haemagogus and Sabethes in the transmission of yellow fever virus (YFV) and the public health impacts of recent YFV epidemics in the Americas, relatively little has been reported on the biology and ecology of these vectors. Many Aedes, Haemagogus and Sabethes spp. in the American tropics inhabit and develop in the forest canopy and are difficult to sample with conventional entomological surveillance methods.

Respiratory rate and heart rate variability (HRV) are studied as stress markers in a database of young healthy volunteers subjected to acute emotional stress, induced by a modification of the Trier Social Stress Test. First, instantaneous frequency domain HRV parameters are computed using time-frequency analysis in the classical bands. Then, the respiratory rate is estimated and this information is included in HRV analysis in two ways: 1) redefining the high-frequency (HF) band to be centered at respiratory frequency; 2) excluding from the analysis those instants where respiratory frequency falls within the low-frequency (LF) band.
